NI's bus interface software products add USB support

27 August 2003 Test & Measurement

National Instruments' NI-Device Version 1.4 and NI-VISA Version 3.0 bus interface software products now support USB. Instrument developers can use NI-Device 1.4 bus interface software to create USB firmware in addition to GPIB and Ethernet firmware for their ANSI/IEEE Standard 488.2 devices.

NI-Device handles most of the IEEE 488.2 protocol requirements for the instrument developer. The software abstracts the communication bus from the instrument-specific firmware so that instrument developers can create bus-independent firmware that adapts to new communication buses while preserving their firmware investment. NI-Device 1.4 enables instrument developers to write firmware for any instrument that runs a Windows 2000/NT/XP/Me/98 operating system when the connectivity interface support is through an NI PCI-based GPIB interface, the NI PCI-8212 GPIB/Ethernet interface or the new NI PCI-8215 GPIB/USB interface. NI-Device 1.4 is also offered in a DDK source-code package for support on non-Windows operating systems.

Engineers can use NI-VISA 3.0 bus I/O software to communicate with instruments that support USB in addition to GPIB, Serial, VXI, PXI and Ethernet. NI-VISA bus I/O software is a comprehensive software package for configuring, programming and troubleshooting USB, GPIB, Serial, VXI, PXI and Ethernet systems. It features a complete set of high-performance routines for industry-standard programming environments and intuitive debugging tools. NI-VISA 3.0 software works with NI LabVIEW, LabWindows/CVI, Measurement Studio and TestStand as well as NI GPIB, VXI and PXI hardware.
